I agree you should press trespassing charges. She needs a quick and curt lesson in boundaries and a reminder that she crossed the wrong ones.
I had the POLICE and AC called on my by my nutter neighbor who was walking her two Chihuahuas down the street in a baby stroller (yes you read that right) , my 6 year old was playing out front in the sprinkler with our 8 month old Boston Terrier (on a leash ) and when she got in front of our house he dragged my daughter over to see the dogs in the stroller.
The neighbor must not have seen me sitting on the porch and proceed to scream and cuss at my daughter to get her f’ing pitbull away from her dogs because he was going to kill them. Then to told her she was going to call the police and have him shot because he was a “dangerous breed”.
I might have come unhinged and said some very un Christian things much to her shock when I stood up from my chair on the porch.
The next day the police and AC showed up because of a dangerous dog call …the embarrassment shown pretty brightly on their faces when I produced this face https://sphotos-a.xx.fbcdn.net/hphotos-ash3/246939_4832094094058_50458344_n.jpg
They laughed pretty heartily when I admitted to going a little overboard with how I spoke to her. The AC officer in his best southern voice said “Well Ma’am I think I’d have been even less restrained.”
